If i have 35% of a phones and its now $78 how much was the phone before the discount

denpristay [2]

Step-by-step explanation:

Multiply $78 by by 65/100 to determine the original price.

78 can be put over 1.

Multiply:

$\frac{78}{1} \times \frac{65}{100} = \frac{5070}{100}$

Simplify by dividing the numerator and denominator by 100:

$\frac{5070 \div 100}{100 \div 100} = \frac{50.70}{1}$

The original price was $50.70.
